摘要:
A load balancing apparatus stores a transfer rule in which a path control identifier for identifying a path for a message sent from a client device is associated with relay device information for specifying a relay device that creates the path control identifier. When receiving a message from the client device, the load balancing apparatus determines whether the message contains the path control identifier. If the load balancing apparatus determines that the path control identifier is contained, the load balancing apparatus specifies, from the transfer rule, relay device information with which the path control identifier is associated and then sends the message to a relay device that is specified by the specified relay device information. In contrast, if the load balancing apparatus determines that the path control identifier is not contained, the load balancing apparatus sends the message to the relay device specified in accordance with a predetermined condition.

A relay apparatus executes a reallocation process so as to transfer data received from an information processing apparatus allocated to the relay apparatus to a destination apparatus. The reallocation process includes the following operations. The relay apparatus determines reallocatability of the information processing apparatus on the basis of a status of receiving transfer data from the information processing apparatus. The reallocatability represents whether the information processing apparatus is reallocatable to another apparatus. The relay apparatus stores reallocatability information indicating the determined reallocatability in a storage unit. The relay apparatus determines whether to reallocate the information processing apparatus on the basis of the reallocatability information stored in the storage unit. The relay apparatus reallocates the information processing apparatus determined to be reallocated.

A relay apparatus for transferring message data received from a client to one of a plurality of servers includes a status management data storage, a transfer rule handling section, and an acknowledgment transmitting section. The status management data storage holds data of an acknowledgment necessity table. The acknowledgment necessity table includes first identification information of a first apparatus to which the relay apparatus acknowledges when the relay apparatus has received first transfer rule notification data from the first apparatus. The transfer rule handling section determines whether the acknowledgment necessity table includes the first identification information identical to second identification information of a second apparatus upon receiving second transfer rule notification data from the second apparatus. The acknowledgment transmitting section transmits acknowledgment data to the second apparatus when the acknowledgment necessity table includes the first identification information identical to the second identification information.

An event controller is caused to function as a receiving unit, a request unit, and a transfer unit. The receiving unit receives an event notification request containing designation information designating a client. The request unit requests notification of one of a plurality of servers as an assignment destination server, based on the designation information, the one providing a service to the client identified by the designation information. The transfer unit transfers the event notification request to the assignment destination server notified in response to the request by the request unit.

An information distributing system comprises a startup condition management device inputting and holding a startup condition per user possessing a user terminal, inputting and holding context per user, and comparing the startup condition with the context for the same user and outputting, when both are coincident with each other, a service startup request including startup condition information and the context, and a service execution device outputting, when receiving the service startup request, a service execution request corresponding to the user terminal or controllable resources associated with the user terminal based on the startup condition information and the context included in the service startup request. The startup condition information can be provided from the user terminal or the service execution device. The service execution device outputs the service execution request through a service execution auxiliary device as required. The context can be provided to the startup condition management device through the user terminal itself or a context collection device.

A method of realizing uniqueness assurance includes: selecting a server to which a first message is to be transferred from multiple servers and transferring the first message to the selected server when the first message is received from a terminal apparatus by a load sharing apparatus; storing a second message that should be transferred to the same server as that of the first server when the second message is received from the terminal apparatus by the load sharing apparatus after the first message is transferred; generating uniqueness assurance information corresponding to the communication protocols corresponding to a session generated by the server to which the first message is transferred, the uniqueness assurance information indicating the correspondence between the session and the message corresponding to the session; and transferring the second message in accordance with the generated uniqueness assurance information if the stored second message exits.
摘要:
One system distributes a request for providing a service using a first communication protocol, from a terminal device to a server selected from among a plurality of servers by a server load balancer in response to the request. A corresponding relation between identification information for identifying a session generated in a distributed server and the server that has generated the session corresponding to the identification information is set in the server load balancer by the service of a second communication protocol as uniqueness assurance information for uniqueness assurance. Thus, when the provision of a service is requested using a second communication protocol by the terminal device, the server load balancer refers to the set uniqueness assurance information and selects the server for providing the service from among the plurality of servers.
